The geometry of Feynman integrals

Rodrigo Pitombo
Abstract
Feynman integrals are the essential building blocks of observables in perturbative Quantum Field Theories. As precision experiments in high-energy physics are becoming more common, understanding the structure of higher loop integrals has become very important from a phenomenology point of view. On the mathematical physics side, such investigations have led to profound connections to geometry. In particular, there is a correspondence between Feynman integrals and algebraic varieties and knowing what geometry a given Feynman integral corresponds to offers invaluable lessons in solving it. In this talk, I will start with a pedagogical review of modern methods to solve higher loop integrals. Then, with a simple example, I will show how one can infer the geometry associated with an integral and discuss some of the implications of this connection.


Junior Strings is a seminar series where DPhil students present topics of common interest that do not necessarily overlap with their own research area. This is primarily aimed at PhD students and post-docs but everyone is welcome.

Dealing with Exam Anxiety

Abstract

This session, led by the Counselling Service,  will guide you through a CBT informed understanding of anxiety, which may arise about exams. The session includes:

  • Psychoeducation - what is happening in the brain and body when we worry about exams
  • Paradox of worry – how more pressure, makes studying less likely
  • Experiential exercises – management strategies to maintain focus and engagement
  • Takeaway tools – a collection of managing stress skills for self-guided practice
  • Practical tips – enhance your exam preparation
